1,2,4,6-Tetraaryl-1,4-dihydropyridines were obtained by the one-pot reaction of chalcones and substituted anilines on the surface of Bi(III)nitrate-Al2O3. The reaction seems to proceed via β-oxygenation of Bi(III) enolised chalcones followed by Michael addition and heteroannulation with simultaneous retro aldol disproportionation. The presence of the ring-activating groups at ortho and para positions in the aniline seems to be essential for the reaction.
